A comen-Amon; on DELAWARE speetivelygu to the 'upperf andi lower;` ende f of e .eu-latei either hoewel-Jeu: or Stammes-at' Y Na-ter being supplied through the coil 15 will be pre-heated as it passes downward and thus will enter the column 11 as hot water. The water supplied to the column 11 will be caused to circulate through the coils 16, entering at the lower ends and discharging at the upper ends. It large quantity of water is supplied, the coils 16 and the column Vwill be lilled with water, but if a limited level was below the lower end of the pipe' then `saturated steam Awould loe discharged upwardly through said pipe. The pipev20 is connected `above the column with a discharge pipe 21 which conducts the'uid'to itsV work. A. pressure gauge 22 may be connected with the pipe 21.? Either saturated steam or hot Vwater is discharged from the upperl end of the column 11 into the upperl ends of the steamecoils 17. As this Huid progresses Y l downwardly in vsaid coils its temperature is raised .so that it is converted intoV super-V heated steam by the time it discharges into the Ts 18. The superheated steam is conducted from the generator through the pipe 19. Ahot water pipe 23 leads from the 'lower end of the column 11for the purpose of conducting hot water therefrom.

n. It is obvious that suiiicient pressureV will be created in the column 11 to force either hot water or saturated steam up through the pipe 20.V It is also apparent thatthe steam generated in the coils 17 will create a back pressure and this pressure will be equalized lthroughout the generator, thus causing all of the Fluids to flow in the direction desired. It is possible to discharge very hot water or saturated steam through the pipe 21 while hot water of a lower temperaturesis discharged through the pipe 28 and superheated steam under relatively high velocity is dispipe 19, but all under an eq ualized pressure.

The fluids supplied by this generator ai'c Aparticularly designed for use in connection with the apparatus covered in the application hereinbefore mentioned. Therefore, it

y is highly desirable toobtain the particular fluids herein set forth and which are not coinmon to an ordinary coillooiler.l The fluid discharged through the: pipe 21 is utilized for forming a detergent solution, while the hotv waterdischarged from the pipe 23 is Aemployedeither to dilute said solution or for washing olf thesurface which has loeen -cleanedywhile the high velocity-steam dis- ,j

charged from the pipe 19 is utilized to impel the detergent solution or the hot washing,

shown a form in which the pickup pipe 2O is omitted and a fluid discharge pipe 21 is connected directly to the upper portion of the column 11. In this form hot water would be dischargedinto the pipe 21" if the column was kept filled, lout in practical Voperation saturated steam and not hot water would be discharged from the top of the column.

Various changes in the size and shape of lthe different parts, as well as modifications and alterations, may be made within the scope of the appended claims.
